STOP-MOTION FOR GRAIN-WEIGHiNG APPARATUS.

SPECIFICATION forming part of Letters Patent No. 332,116, dated December 8, 1885,

Application filed June 26, 1885. Serial No. 169,803. (No model.)

To aZZ whom it may concern:

Be it known that I, CHARLES SEEssLE, of the city, county, and State of New York, have invented certain new and usefulImprovements in Stop-Motions for Grain-Weighing Apparatus, of which the following is a specification;

This invention relates to an improved stopmotion for automatic grain weighing machines, and more especially to the grain-weighing machine for which Letters Patent have been granted to me heretofore under date of May 5, 1885, No. 317,220, so that the machine is brought automatically to a stop after a determined quantity of grain has been weighed; and the invention consists of astop-motion for automatic grain-weighing machines, in which the scale-beam of the machine is connected by suitable transmitting mechanism with an intermittingly-rotating cylinderhaving a longitudinal tooth and a shaft that is threaded on the outer end, the tooth engaging a gear-wheel of a second cylinder sliding on a fixed rod, said second cylinder being engaged by the forked end of a laterally-traversing screw-arm that is moved forward by the threaded end of the shaft of the first cylinder. The lower cylinder is provided with numerals arranged in a spiral line on the surface of the same, and provided with a nose at the opposite end, which nose engages a laterally guided and spring-cushioned pusher-rod that operates a fulcrumed lever-rod which releases a droplever having pawls at the side of the hopper of the weighing-machine, said pawls engaging a stop on an upwardly-extending arm of the oscillating supply-valve, so as to interrupt the operation of said valve and hold it in horizontal position when the machine has weighed the required quantity of grain.

In the accompanying drawings, Figure 1 represents a side elevation of a grain-weighing machine with my improved stop-motion, showing its connection with the scale-beam Fig. 2 is a side elevation of the registering mechanism of the stop-motion drawn 011 a larger scale, and Fig. 3 an end view of Fig. 2. Fig. 4 is an end elevation of the grain-weighing machine and stop-motion. Fig. 5 is a vertical transverse section of the register of the stopmotion on line x m, Fig. 6, including the faceplate and cross-section of the pusher-rod and stop-valve. Fig. 6 is an elevation of the reg ister of the stop motion drawn on a larger scale, and with parts broken off. Fig. 7 is a detail side view of the gear for operating the registering-cylinders of the stop-motion.

Similar letters of reference indicate corresponding parts.

In the drawings, A represents a scale-beam of a grain-weighing machine, which beam is arranged with an extension-arm, a, that is connected by a pivotrod, b, with an oscillating arm, d, (see Fig. 3,) having at its opposite end a weighted pawl, d. The oscillating arm (1 turns loosely on the end of a horizontal shaft, B, which is supported in bearings of a casing, C, within which the registering mechanism of the stop-motion and the counter of the weighing machine are arranged. The weighted pawl d engages a ratchet-wheel, d*, that is keyed to the shaft B. A second shorter connecting-rod, d connects the arm (I with a second oscillating arm, d, having a springpawl, (i which latter engages the teeth of a ratchet-wheel, d, on the shaft C of the counter C, which is of any approved construction, and located at the upper part of the casing C, as shown in Figs. 1, 2, and 3.

When the weighted end of the scale-beam A is raised by the weight of the grain in the bucket, the connecting-rods b and d and the arms d and cl operate the pawls d and d and turn the ratchet-wheels d d for the distance of one tooth. WVhen the bucket is discharged, the weighted end of the scale-beam descends, while the extensiona -m is raised. so that the pawls d d are lifted and moved forward into engagement with the next adjoining teeth of the ratchets (l d,into position to be turned by the next motion of the scale-beam,as described.

To the shaft B is keyed a cylinder,B,which receives intermittent rotating motion by the scale-beam and intermediate pawl-an dratchet mechanism. The shaft B is made of double the length of the cylinder B and screw-threaded at that end not covered by said cylinder. The shaft B is extended through the casing C and provided with a handcrank, B for turning the same from the outside. The cylinder B has at the inner end, next to the threaded part of the shaft B, the numerals 0 to 9 arranged on its circumference, of which one at a time is visible through a front opening of the casing O. The cylinder B engages by a longitudinal tooth, e, a gear-wheel, e,with ten notches, as shown in Fig. 6, that is attached at the end of a second cylinder, D, that is arranged below the cylinder B and made equal' in length therewith. The cylinder D is placed loosely on a shaft, D, that is firmly secured to the casing O. The numbers from 1 to 1000 are arranged in a spiral line on the perimeter of the cylinder D,which is turned for the distance of one tooth when the cylinder B has completed one entire rotation. At the opposite end of the cylinder D is arranged a fixed nose, f, and adjoining to the nose f a grooved collar, f, is attached to the cylinder D,which is engaged by the forkshaped end of atraversingarm,f, the opposite end of which is made in the shape of a nut, f, that is caused to move on the threaded end of the shaft B by the turning of the same. The forked arm f moves thereby the cylinder D forward on its supporting-shaft D until the arm f arrives at the shoulder f on the opposite side wall of the casing O. The longitudinal tooth e of the cylinder 13 is kept in mesh with the gearwheel 0 throughout the traversing motion of the cylinder D. The numbers on the cylinder D are visible successively through a second opening in the front wall of the casing O,said second opening being vertically below the opening for the numerals on the cylinder B, as shown in Fig. 2.

When it is desired that the grainweighing machine is to weigh a determined quantity of grain,the cylindersB and D are first adjusted to the number required by turning the shaft B by the hand-crank in an opposite direction to the motion imparted to the same by the transmitting mechanism until the required number appears in the openings of the inclosing-casing. The successive weighing of grain by the machine turns the cylinder B and moves the cylinder D from the right toward the left until it arrives at zero,and is stopped by contact with the opposite side wall of the casing 0. When the zero-figure of the cylinder D appears in the front opening of the casing, the nose f engages the rounded off head of a sliding and spring-cushioned pusher-rod, g, which is clamped at its outer end to a stop-sleeve, 9, that is pivoted to one end of a fulcrumed lever, F, the opposite end of which engages a drop lever, F, that is pivoted at its rear end to the side wall of the hopper of the grain-weighing machine, and provided at its front end with a handle for setting the drop-lever. When the lever F is actuated by the nose f, the outer end of the same clears the drop-lever F and permits the latter to drop. The d rop-leveris provided with two stop-pawls, h h, that engage a central stop, h, of an upwardly-extending arm, H, of the oscillating supply-valveH of the grain-weighing machine as soon as the drop-lever is released from the lever F. As soon as the pawls h of the drop-lever F engage the central stop, it, of the upwardly-extending arm H of the supply-valve H the latter is held in horizontal position, and thereby the action of the grainweighing machine interrupted. This takes place in a reliable and automatic manner whenever the required quantity has been passed through the weighing-machine, so that the same is adapted for weighing of determined quantities of grain, as required in breweries, distilleries, and for other purposes.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination, with a scale-beam and suitable transmitting mechanism, of a stopregister consisting of an axially-turning cylinder and intermittingly-rotating and laterally-sliding cylinder, said cylinder having a projecting nose, a guided and spring-cushioned pusher rod actuated by said nose, a supply-valve, and a lever mechanism actuated by the pusher-rod for stopping said supplyvalve and arresting the motion of the weighing apparatus, substantially as set forth.
